A QUANTITATIVE DESCRIPTION OF DAMAGE AND ITS EVOLUTION OF SFRC UNDER CYCLIC LOADS

Based on an experimental investigation of damage performance of SFRC under axial compressive cyclic loads, a quantitative description of damage and its evolution of steel fibre reinforced concrete (SFRC) is presented in this paper. An equation which characterizes the damage evolution of SFRC is proposed in the paper. It is found that the theoretical results are in good agreement with the experimental results.
